In some demonstrative embodiments, an architecture of a layer one (PHY) of a transmitter of a multi-band aggregation may be configured to support different transmission configurations, e.g., per each frequency band, for example, since different frequency bands may have one or more different parameters, e.g., available bandwidth (BW), channel condition, and the like.

In one example, a STA may communicate over a multi-band aggregation including a first channel in the 6 GHz frequency band and a second channel in the 5 GHz frequency band. According to this example, if communication over the first channel experiences stronger interference than the second channel, the architecture may be configured to use different modulation and coding schemes (MCS), e.g., lower MCS on the first channel, and/or to decrease the bandwidth for the first channel, e.g., from a BW of 160 MHz to a BW of 80 MHz or lower, for example, in order to increase a Signal to Noise Ratio (SNR) of transmission over the first channel, e.g., using a lower BW transmission.

In some demonstrative embodiments, devices 102 and/or 140 may implement a PHY transmitter baseband architecture, which may be configured to support a layer-1 multi-band aggregation, e.g., using different transmission configurations, for example, different bandwidths, different MCSs and the like, for each frequency band, e.g., as described below.

In one example, the transmissions over the non-contiguous 160 MHz channel bandwidth may support using only the same MCS on the first and second 80 MHz channels.

In another example, the transmissions over the non-contiguous 160 MHz channel bandwidth may not support multi-band aggregation.

In some demonstrative embodiments, the PHY transmitter baseband architecture may support a layer-1 multi-band aggregation having different transmission configurations per band, for example, different bandwidth, different MCS and the like, e.g., as describe below.

In some demonstrative embodiments, the PHY transmitter baseband architecture may support a single-band 320 MHz PHY TX baseband architecture, e.g., as describe below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate an OFDM transmission, e.g., as described below.

In some demonstrative embodiments, device 102 may be configured to transmit the OFDM transmission, and/or device 140 may be configured to receive the OFDM transmission, e.g., as described below.

In some demonstrative embodiments, transmitter 118 may be configured to process and transmit the OFDM transmission, e.g., as described below.

In some demonstrative embodiments, transmitter 118 may include a PHY TX architecture configured to support multi-band aggregation, which may aggregate, for example, two 160 MHz channels from two different bands, e.g., in a non-contiguous allocation, for example, to form a 320 MHz, e.g., 160 MHz+160 MHz, bandwidth PPDU transmission, e.g., as described below.

In some demonstrative embodiments, transmitter 118 may include a PHY TX architecture configured to support a multi-band non-contiguous aggregation, for example, for other BW combinations, e.g., including 80 MHz+80 MHz, 80 MHz+160 MHz, 40 MHz+80 MHz, and/or any other combination, e.g., as described below.

In some demonstrative embodiments, the PHY TX architecture may support different transmission configurations, e.g., bandwidth, MCS and the like, for example, on each band, which may allow, for example, to optimize transmission on each band and/or to allow per-band link adaptation, which may optimize system throughput, e.g., over all bands.

In one example, the PHY TX architecture may support a non-contiguous configuration, which may support non-equal MCS on the different frequencies, e.g., as described below.

In some demonstrative embodiments, the PHY TX architecture may support a 320 MHz transmission, e.g., at a contiguous mode and/or a non-contiguous mode, for a single band, for example, for the 6 GHz frequency band, e.g., as described below.

In some demonstrative embodiments, the PHY TX architecture may enable multi-band aggregation and/or may support different modulation and coding schemes, e.g., to enable a transmitter, e.g., an AP, to optimize one or more transmission parameters, for example, based on channel conditions and the like on each band, e.g., as described below.

In some demonstrative embodiments, the multi-band aggregation may improve throughput performance, for example, in Wi-Fi systems.

In some demonstrative embodiments, two different multi-band PHY TX baseband architectures may be utilized for implementing a PHY TX baseband architecture for multi-band aggregation, e.g., as described below.

In some demonstrative embodiments, each of the two different multi-band PHY TX baseband architectures may include a segment parser (also referred to as a “Multi-band 160 MHz Segment Parser”), for example, to support different modulation and coding on each band, e.g., as described below.

In one example, the segment parser may receive data bits, e.g., from a scrambler, may calculate a total number of data bits per OFDM symbol, and may split the data bits into two 160 MHz segments for each band, e.g., as described below.

In some demonstrative embodiments, transmitter 118 may implement a multi-band PHY TX architecture, e.g., including one of the two architectures described below, for example, for multiband operations, e.g., as described below.

In one example, each of the two multi-band architectures may implement two 160 MHz segments, e.g., 160 MHz+160 MHz. However, the two multi-band architectures may be configured to support other bandwidth mixes as well, e.g., 80 MHz+160 MHz, 40 MHz+80 MHz, and the like.

In some demonstrative embodiments, a first multi-band architecture may utilize a contiguous 160 MHz definition, e.g., for a contiguous 160 MHz channel to be used on each band, e.g., as described below with reference to FIG. 2.

In some demonstrative embodiments, a second multi-band architecture may utilize a non-contiguous channel including a first 80 MHz channel BW and a second 80 MHz channel BW in each band. For example, for each band the 160 MHz channel BW may be split into two non-contiguous 80 MHz channels, e.g., as described below with reference to FIG. 3.

In one example, the second multi-band architecture may be more complicated than the first multi-band architecture, e.g., from an implementation perspective. However, by implementing an improved technology, the second multi-band architecture may be versatile to achieve an increased use of an available spectrum.

In some demonstrative embodiments, the PHY TX architecture may be implemented according to a single-band architecture for operation over a 320 MHz channel bandwidth, e.g., on one band, for example, the 6 GHz frequency band, e.g., as described below.

In some demonstrative embodiments, a first single-band architecture may utilize two 160 MHz contiguous allocations, for example, to be used in separate channels to provide two non-contiguous 160 MHz channels to form a 320 MHz channel, e.g., as described below with reference to FIG. 4.

In some demonstrative embodiments, a second single-band architecture may utilize two continuous 160 MHz channels to form one contiguous 320 MHz channel, e.g., as described below with reference to FIG. 5.

In some demonstrative embodiments, the PHY TX architecture may enable multi-band aggregation and may support different modulation and coding schemes, for example, to enable a transmitter, e.g., an AP, to optimize transmission parameters on each band, for example, based on channel conditions, and the like. These capabilities may enable layer-1, e.g., PHY-layer, multi-band aggregation to improve throughput performance in Wi-Fi systems.

In some demonstrative embodiments, the PHY TX architecture may include a multi-band 160 MHz segment parser, e.g., as described below.

In some demonstrative embodiments, transmitter 118 may include a segment parser 110, e.g., the multi-band 160 MHz segment parser, as described below.

In some demonstrative embodiments, the segment parser 110 may be configured to parse scrambled data bits of a PPDU into a first plurality of data bits and a second plurality of data bits.

In some demonstrative embodiments, the PPDU may be transmitted in an OFDM transmission over an aggregated bandwidth including a first channel in a first frequency band and a second channel in a second frequency band, e.g., as described below.

In some demonstrative embodiment, the first plurality of data bits may be transmitted over the first channel in the first frequency band, e.g., as described below.

In some demonstrative embodiments, the second plurality of data bits may be transmitted over the second channel in the second frequency band, e.g., as described below.

In one example, the multi-band 160 MHz segment parser may split data bits in each multi-band aggregated OFDM symbol to different bands, for example, based on one or more per-band configurations. For example, the multi-band 160 MHz segment parser may be extended, for example, to support various BW combinations, e.g., as described below.

In one example, the multi-band 160 MHz segment parser may group the data bits for transmission on the two bands, e.g., as described below.

In some demonstrative embodiments, transmitter 118 may include a first baseband processing block configured to encode and modulate the first plurality of data bits, for example, according to a first OFDM Modulation and Coding Scheme (MCS) for transmission over the first channel in the first frequency band, e.g., as described below.

In some demonstrative embodiments, transmitter 118 may include a second baseband block configured to encode and modulate the second plurality of data bits, for example, according to a second OFDM MCS for transmission over the second channel in the second frequency band, e.g., as described below.

In some demonstrative embodiments, the segment parser 110 may be configured to determine a first number of data bits per OFDM symbol, for example, based on one or more first parameters corresponding to the first channel in the first frequency band, e.g., as described below.

In some demonstrative embodiments, the segment parser 110 may be configured to determine a second number of data bits per OFDM symbol, for example, based on one or more second parameters corresponding to the second channel in the second frequency band, e.g., as described below.

In some demonstrative embodiments, the segment parser 110 may be configured to parse the scrambled data bits of the PPDU into the first plurality of data bits based on the first number of data bits per OFDM symbol, and to parse the scrambled data bits of the PPDU into the second plurality of data bits based on the second number of data bits per OFDM symbol, e.g., as described below.

In some demonstrative embodiments, the one or more first parameters may include a number of coded bits per subcarrier for the first channel in the first frequency band, a number of OFDM subcarriers for the first channel in the first frequency band, and/or or a coding rate for the first channel in the first frequency band, e.g., as described below.

In other embodiments, the one or more first parameters may include any other parameters, e.g., as described below.

In some demonstrative embodiments, the one or more second parameters may include a number of coded bits per subcarrier for the second channel in the second frequency band, a number of OFDM subcarriers for the second channel in the second frequency band, and/or a coding rate for the second channel in the second frequency band, e.g., as described below.

In other embodiments, the one or more second parameters may include any other parameters, e.g., as described below.

In some demonstrative embodiments, the segment parser 110 may be configured to determine a total number of scrambled data bits per OFDM symbol to be transmitted over the aggregated bandwidth, for example, based on the first number of data bits per OFDM symbol and the second number of data bits per OFDM symbol, e.g., as described below.

In some demonstrative embodiments, the segment parser 110 may be configured to group the scrambled data bits of the PPDU into a plurality of data bit groups, e.g., as described below.

In some demonstrative embodiments, a group of the plurality of data bit groups may include the total number of scrambled data bits per OFDM symbol, e.g., as described below.

In some demonstrative embodiments, the segment parser 110 may be configured to parse the group into the first plurality of data bits and the second plurality of data bits, e.g., as described below.

In some demonstrative embodiments, the segment parser 110, e.g., the “Multi-band 160 MHz Segment Parser”, may separate the data bits of the OFDM symbol into two 160 MHz sub-blocks for each band, e.g., the first and second baseband blocks.

In some demonstrative embodiments, the segment parser described herein may provide one or more technical advantages, e.g., compared to “an IEEE802.11ac Segment Parser”, e.g. a segment parser in accordance with the IEEE802.11ac Specification. For example, the segment parser described herein may support different coding and modulation on each band, and/or may split the data bits of the OFDM symbol before encoding, e.g., as described below.

In some demonstrative embodiments, the segment parser 110 may receive, e.g., from a scrambler, output data bits of the OFDM symbol and may group them, for example, for each multi-band aggregation OFDM symbol, e.g., as described below.

In some demonstrative embodiments, the segment parser 110 may calculate a total number of data bits for each OFDM symbol, denoted as “N_(DBPS)”, e.g., as follows: N _(DBPS)=Σ_(i) N _(DBPS)1  (1) wherein N_(DBPS) denotes a number of data bits per symbol for an i-th band, denoted “i”.

In some demonstrative embodiments, the number of data bits per symbol N_(DBPS,i) may be determined, e.g., as follows:

$\begin{matrix} {N_{{DBPS},i} = \frac{N_{{BPSC},i} \times N_{{SC},i}}{R_{i}}} & (2) \end{matrix}$ wherein N_(BPSC,i) denotes a number of coded bits per symbol per subcarrier on the band i, N_(SC,i) denotes the number of OFDM subcarriers on the band i, and R_(i) denotes a coding rate on the band i.

In other embodiments, the number of data bits per symbol N_(DBPS,i) may be determined, for example, according to any other calculation and/or using any other criteria.

In some demonstrative embodiments, once the segment parser 110 groups the data bits per OFDM symbol, the segment parser 110 may split the data bits to each band, for example, by sending N_(DBPS,i) bits to the band i.

In one example, the segment parser 110 may use a simple block-wise round robin algorithm, for example, for splitting of the data bits. For example, the segment parser 110 may send the first N_(DBPS,0) data bits to band 0, the next N_(DBPS,1) bits data bits to band 1, and so on.

In another example, the segment parser 110 may use any other algorithm, for example, to split the data bits. For example, the segment parser 110 may split the data bits based on any other metric, and/or the segment parser 110 may divide the data bits into two contiguous blocks, and may send each block to each of the bands.

In some demonstrative embodiments, once the data bits are split into two different bands, the data bits may be encoded and modulated using an MCS, e.g., assigned to each band.

In some demonstrative embodiments, one or more transmission parameters of the data bits may be determined, for example, in a MAC processor, e.g., controller 124.

In some demonstrative embodiments, the MAC processor may send to the PHY layer configuration information, e.g., the one or more transmission parameters, for example, as a part of a TXVECTOR element or a TRIGVECTOR element.

In other embodiments, the MAC processor may send the configuration information to the PHY layer using any other method and/or as part of any other element.

In one example, an MCS to be used on a band may be determined, for example, based on link quality indicators on each band, e.g., a received signal strength indicator (RSSI), a Signal to Noise (SNR) indicator, a Block Error Rate (BLER) indicator and the like, and/or based on band congestion or availability.

In other embodiments, any other method, parameters, indicators, metrics and/or mechanism may be used to determine the MCS.

In some demonstrative embodiments, transmission configuration for each band, e.g., the one or more transmission parameters, may be indicated in a signaling field in a PHY preamble, e.g., a High Efficiency (HE) SIG-A PHY preamble in accordance with an IEEE802.11ax Specification.

In some demonstrative embodiments, a signaling field may be defined for a 20 MHz bandwidth and may be duplicated on each band. The signaling field may indicate transmission configurations per band, e.g., BW, MCS, and the like.

In other embodiments, any other signaling may be defined. For example, separate signaling fields may be defined per band, e.g., to enable asynchronous multi-band aggregation.

In some demonstrative embodiments, the PHY TX architecture may be extended to support different bandwidths on different bands, e.g., 80 MHz on the 5 GHz band and 160 MHz on the 6 GHz band. According to this example, the number of OFDM subcarriers on the band N_(SC,i) may be different for each band, for example, depending on the bandwidth.

In some demonstrative embodiments, transmitter 118 may be configured to transmit the PPDU in an OFDM transmission over an aggregated bandwidth including a first channel in a first frequency band and a second channel in a second frequency band, e.g., as described below.

In some demonstrative embodiments, the first channel may include a first aggregated channel including an aggregation of a first channel bandwidth in the first frequency band and a second channel bandwidth in the first frequency band, and the second channel may include a second aggregated channel including an aggregation of a first channel bandwidth in the second frequency band and a second channel bandwidth in the second frequency band, e.g., as described below.

In some demonstrative embodiments, as shown in FIG. 6, the four blocks 625 may be distributed across the whole 160 MHz bandwidth 628 and/or may not be continuous to each other.

In some demonstrative embodiments, as shown in FIG. 6, tone plan 620 may include a DC portion 629 between second portions of the 1992 tone RU 626.

In some demonstrative embodiments, as shown in FIG. 6, DC portion 629 may include 5 DC tones, and 9 null tones 627 on a first side of the 5 DC tones, 9 null tones 627 on a second side of the 5 DC tones.

In other embodiments, any other allocation of the DC tones and the null tones may be used.

In some demonstrative embodiments, reserving the residual tones 624 in tone plan 620, e.g., instead of aggregating the residual tones 624 with the 1992 tones RU 626, for example, to form a larger RU, may enable to keep the same function of the residual tones 624 in tone plan 610, e.g., for single user and multi-user allocation in the 160 MHz BW.

In some demonstrative embodiments, as shown in tone plan 630, residual tones 624 may not be reserved, such that a 2020 tone RU 636 may be formed, which may maximize an efficiency of tone plan 630, but lose a function of residual tones 624, for a multi-user communication.

In some demonstrative embodiments, as shown in FIG. 6, tone plan 630 may include DC portion 632 and guard tones 612.

In some demonstrative embodiments, as shown in FIG. 6, DC portion 632 may include five DC null tones.

In some demonstrative embodiments, the DC nulls tones 632 in tone plan 620 may include seven DC null tones.

In one example, a carrier frequency offset in tone plan 630 may be considered to be a same as tone plan 610, while an oscillator may be between 6 GHz-7 GHz in a next generation WiFi, e.g., a 20% increase for carrier frequency offset (CFO). For example, if the number of DC null tones in DC portion 632 is changed from 5 to 7, the number of tones 627, e.g., around the DC null tones, may be changed from nine tones to eight tones, for example, in order to keep the same number of tones in the middle of 2020 tone RU 636. For example, both tone plans 620 and 630 may include 23 tones in the middle, e.g., 5+9*2=23 in tone plan 620, and 7+8*2=23 in tone plan 630. According to this example, a number of tones in 2020 tone RU 636 may be changed from 2020 tones to 2018 tones in total.

In some demonstrative embodiments, the 320 MHz tone plans 720 and 730 may be configured to comply with a 160 MHz tone plan 710, e.g., the tone plan 620 (FIG. 6).

In some demonstrative embodiments, as shown in FIG. 7, tone plan 720 may be based on the tone plan 620 (FIG. 6), e.g., the first 160 MHz tone plan.

In some demonstrative embodiments, as shown in FIG. 7, tone plan 720 may include a first portion 741, a second portion 742, a third portion 743, and a fourth portion 744, e.g., each including a 996-tone RU.

In some demonstrative embodiments, as shown in FIG. 7, boundaries of tone plan 720 may be aligned with tone plan 710. Therefore, the boundary of tone plan 720 may be aligned with the boundary of tone plan 610 (FIG. 6), e.g., a 80 MHz tone plan in accordance with an IEEE80211ax Specification, which may enable to reuse the 80 MHz tone plan, e.g., the tone plan 610 (FIG. 6).

In some demonstrative embodiments, as shown in FIG. 7, tone plan 720 may include null portions 711 (also referred to as “reserved tones”), e.g., 5 nulled tones, which may be excluded, for example, when reusing the 80 MHz tone plan, e.g., the tone plane 610 (FIG. 6).

In some demonstrative embodiments, as shown in FIG. 7, tone plan 720 may include a first non-data portion 723 and a second 725 non-data portion (also referred to as “reserved tones”). The first non-data portion 723 may be between portions 741 and 742 of RU 724, and the second non-data portion 725 may be between portions 743 and 744 of RU 724.

In some demonstrative embodiments, as shown in FIG. 7, tone plan 720 may include 84 reserved tones, e.g., including non-data portion 723 and/or 725 and null portions 711, which may be marked as nulled tones.

In some demonstrative embodiments, usages of the 84 nulled tones may be similar to the usage discuss above, e.g., with respect to residual tones 624 (FIG. 6). For example, the 84 reserved tones may be used for control signaling, pilots and/or any other usage, e.g., instead of nulling the 84 tones.

In some demonstrative embodiments, devices 102 and 140 (FIG. 1) may use tone plan 720 to communicate a single user communication over a 320 MHz channel BW, e.g., as described below.

In some demonstrative embodiments, a first RU unit size may be introduced for communication over the 320 MHz channel BW, e.g., as described below.

In some demonstrative embodiments, as shown in FIG. 7, tone plan 720 may include a wide RU unit 724, e.g., including 3984 tones.

In some demonstrative embodiments, as shown in FIG. 7, RU unit 724 may reserve the 84 nulled tones. RU unit 724 may enable a function of the reserved 84 tones for both single user and multi-user operation.

In some demonstrative embodiments, a second RU unit size may be introduced for communication over the 320 MHz channel BW, e.g., as described below.

In some demonstrative embodiments, as shown in FIG. 7, RU unit 734 may combine the 84 reserved tones with the 3984 tones of RU unit 724, for example, to form a larger RU having 4068 tones. RU unit 734 may maximize an efficiency of tone plan 730.

In one example, RU unit 724 may include 4066 tones, for example, if a number of DC nulls 736 is 7.

Referring back to FIG. 1, in some demonstrative embodiments, devices 102 and/or 140 may communicate according to a tone plan over a 160 MHz channel BW and/or 320 MHz channel BW, e.g., as described above with reference to FIG. 6 and FIG. 7.

In some demonstrative embodiments, it may be advantageous not to use small size RUs, e.g., a 26 tone RU and or 52-tone RU, e.g., as described below.

In one example, WiFi devices may target for large bandwidth and high throughput, e.g., using the 160 MHz channel BW and/or a 320 MHz channel BW. According to this example, disabling the small size RUs may simplify a scheduling, resource allocation signaling, and/or channel quality feedback.

In some demonstrative embodiments, disabling the small size RUs may cause a technical problem of how to utilize 26-tone RUs, which are located between 106 tone RUs.

In some demonstrative embodiments, devices 102 and 140 may be configured to aggregate the 26-tone RUs, for example, to form a distributed 52-tone RU, e.g., using two 26-tone RUs, or a distributed 106-tone RU, e.g., using four 26-tone RUs.

In other embodiments, any other size of a distributed RU may be used.

In some demonstrative embodiments, aggregating the 26-tone RUs may obviate a need to create a new RU size.
